Answer 1

Morphological characters of organisms have been used extensively both for producing classification and and for diagnostic purposes.The largest unit of classification is a Kingdom.

Complete answer:

The four kingdoms recognised by Copeland are :1.Monera(Mychota), including prokaryotes (bacteria and cyanobacteria), 2.Protista,including eukaryotic organisms not having the characters of typical plants and animals, such as red and brown algae,fungi and protozoa ,3. Plantae(Metaphyta), including plants,and 4. Animalia(Metazoa), including multicellular animals.

Whittaker proposed the five kingdom classification.He classified them as : Monera - primarily prokaryotic organisms. Protista - primarily unicellular forms. Fungi - eukaryotic,multicellular heterotrophic organisms which obtain nutrition by extracellular digestion absorption of organic matter. Plantae - multicellular,photosynthetic forms. Animalia - multicellular animals that are characterised by their nutritional habits they ingest other living organisms.

Three kingdom classification was proposed by E.Haeckel.Kingdom protista included those organisms that can be differentiated from plants and animals by their lack of morphological specialization ,most of them being unicellular.

In two kingdom classification all organisms were placed in either one of the two kingdoms,the plant kingdom(kingdom plantae)and the animal kingdom (kingdom animalia)..the animal kingdom includes unicellular protozoans and multicellular metazoans,whereas the plant kingdom includes all other organism-prokaryotes(bacteria)and eukaryotes photosynthetic and non photosynthetic fungi,unicellular as well as multicellular forms.It was proposed by C.Linnaeus

Hence the correct option is C. A-4,B-1,C-2,D-3

Note: Not only morphological differences are used in classification but also the taxonomic ,phylogenetic,mode of nutrition and digestion processes are used as a reference.
